What's the problem? That joist is supported...by the floor...

The easiest thing to do is sister another 2X4 stud next to the
existing one. Hammer it in and it will bring up the floor, or use a
jack to raise the floor while you put in the stud.

That is the correct way to do it. Also if you look at the bent nails under
the sagging support beam you will see that there used to be a stud under the
end. It is apparent that it has been removed by someone. Was that someone
you?
